Combine the vinegar, water, sugar, and salt in a medium nonreactive saucepan, and bring to a boil. Pour the hot brine over the beans to cover by 1/2 inch. Leave 1/2 inch of headspace between the top of the liquid and the lid.

Can: Use the boiling-water method. Release trapped air. Wipe the rims clean; center lids on the jars and screw on jar bands. Process for 15 minutes. Turn off heat, remove canner lid, and let jars rest in the water for 5 minutes. Remove jars and set aside for 24 hours. Check seals, then store in a cool, dark place for up to 1 year.

Note: The boiling-water method is necessary to tenderize these cold-pack pickles.
